Ekadashi is the eleventh day of each lunar month and two ekadashi come in one month according to positions of the moon. Each ekadashi fasting come after around 15 days of previous one. Ekadashi fasting is taken from sunrise on the Ekadashi day to sunrise on the following Ekadashi day. During the fasting, people don't take even a drop of water.

Parana means breaking the fast. Ekadashi Parana is done after sunrise on next day of Ekadashi fast. It is necessary to do Parana within Dwadashi Tithi either Dwadashi is over or at once after sunrise. Not doing Parana within Dwadashi is similar to an offence.
